Suppose the process was carried out at 850∘. After a review of the performance of the tool, the design engineers decide that there needs to be a concentration of 0.60% at a depth of 3 mm. The surface concentration remains Cs=2.00% and the initial concentration remains C0=0.20%. The treatment time must be 30 hours for the new process. What must the new annealing temperature be? Assume the activation energy for the diffusion is Ed=80,500J/mole.
Express your answer to three significant figures.

can you solve this pls i cant solve

it is a good conductor

explanation:

indium, and thallium have three electrons i think

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
